go-fuzz is a coverage-guided fuzzing tool for testing Go packages with randomized inputs. It is mainly useful for hardening code that parses complex text or binary inputs, such as data accepted over a network.
Use cases
- fuzz test a Go parser for crashes and panics
- harden a network-facing input parser against malicious data
- find hangs and memory blowups in Go deserialization code
- verify round-trip serialize/deserialize consistency in Go
- differential-test two Go implementations against the same inputs
When to choose
- you need coverage-guided fuzzing for Go packages
- you want to test parsers of complex text or binary formats
- you are hardening code that accepts untrusted input
When to avoid
- you are fuzzing non-Go code
- you want native Go 1.18+ built-in fuzzing support instead of a third-party tool
- you need to fuzz package main code
